LAMP SHADE lAND TESTER.

To all whom it may concern:

Be it known that I, VIRGIL A. GUY, a citizen of the United States,residing at Englewood, in the county of Arapahoe and State of Colorado,have invented certain new and useful Improvements in Lamp Shades andTesters; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable othersskilled inthe art to which it appertains to make and use the same.

The present invention relates to a device for use with an electric lampfor the pur pose of shading same and supporting the lamp in a convenientmanner, as well as enabling the lamp to be used for testing electricalcircuits, whereby the device is conveniently used in doing work ormaking repairs on an automobile, as well as for testing electricalcircuits thereof.

The invention has for its object the provision of such a deviceincluding a shade for the lamp having means for engaging the socketmember or sleeve of the lamp, and means for supporting the shade andenabling electrical circuits to be tested, so that the device isusefulfor making repairs or adjustmentson an automobile in the dark, as wellas enabling the ignition circuit, illuminating circuits and the like tobe tested.

With the foregoing and other objects in view, which'will be apparent asthe description proceeds, the invention resides 1n the construction andarrangement of parts hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is clamedwithout departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein'Figure 1 is a front view of the device as applied to the lamp socketmember or sleeve, showing the electrical circuit in diagram.

Fig. 2 is a view taken at right angles to the line of view in Fig. 1,showing the shade in longitudinal section.

Fig. 3 is a cross section on the line 3--3 of Fig. 1.

The device is used with a lamp socket member or sleeve 5 in one end ofwhich the lamp 6 is fitted and secured, and in the other end of whichmember or sleeve a removable plug 7 is fitted and secured for theconnection of an electrical conductor or wire 8 to one terminal of thelamp. Said conductor 8 Specification of Letters Patent, Patenid NOV. 11921 Application filed June 4, 1920. Serial No. 386,458.

is connected through battery 9 to ground, as

at 10, such as the frame of an automobile.

In carrying out the invention, there is provided a dished metal shade 11to sur- "round the lamp with one side of the shade open for directingthe light rays to the point desired. The inner end of the shade 11merges into the neck or clamp 12 of reduced size and extending throughan arc of slightly greater than one half of a circle to snugly embracethe member or sleeve 5 for holding the shade in position over the lamp.In order to more firmly secure the shade to the socket, the edges of theneck or clamp 12 have outstanding ears 13 through which a bolt 14extends, whereby said bolt in being tightened will contract the neck orclamp 12 to firmly embrace the member 5.

A spindle 15, formed from wire or other suitable material, projectslongitudinally outward from the outer end of the shade 11, and isprovided at it basal end with a curved portion 16 soldered, welded orotherwise secured to the shade 11 at one side, and terminating in anoffset portion or hook 17 at said side of the shade. The shade 11 inclamping the member or sleeve 5 will be electrically connected to thecorresponding terminal ,of the lamp 6, and the spindle 15 and hook 17are also in electrical connection with said .shade and lamp, so thatwhen the hook or spindle are used for supporting the lamp from the frameof the automobile or other part in electrical connection therewith, thiswill close the circuit of the lamp 6 to keep it lighted. The hook 17 canbe conveniently used for hanging the shade and lamp up at various pointson the automobile, and the spindle 15 can be inserted in a hole orbetween two parts for supporting the shade and lamp, when the hook 17cannot be used, sothat said spindle and hook will enable the lamp to besupported at the various points of the machine in a convenient mannerfor directing the light to the point at which work is being done.

The spindle 15 is also used to advantage in testing the electricalcircuits of the automobile. The end of the spindle is pointed, so as tobe readily engaged with the conductors or wires of the several circuits,..for testing same. Thus, if the spindle engages a conductor which isgrounded, the lamp 6 will be lighted, whereas if the conductor is in anopen circuit, the lamp will remain extinguished. It is thus possible totest the several circuits for grounds, short circuits, open circuits andthe like. The spindle projecting longitudinally beyond the shade andsocket member in longitudinal alinement with said member, enables thesocket member to be readily held in the hand for directing the spindleto the wires or points where tests are to be made.

Having thus described the invent on, what is claimed as new is 1. Adevice of the character described comprising a lamp shade havingmeansfor embracing a lamp socket member for electrical connection with oneterminal of the lamp, and means on said shade in electrical connectiontherewith for supporting the shade and for engaging conductors ofelectrical circuits for testing same.

2. A device of the character described comprising a lamp shade mergingat its inner end into a neck of arcuate section and adapted to snap overand embrace a lamp socket member for electrical connection with oneterminal of the lamp, and means on the shade in electrical connectiontherewith for supporting the shadevand for engaging conductors ofelectrical circuits for testing same.

A device of the character described comprising a dished lamp shademerging at its inner end to a, reduced neck of arcuate section adaptedto clamp over and embrace a, lamp socket. member, said neck having earsat its edges,vaclamping member' ex tending through. said ears forcontracting the neck to embrace said member for 'elec trical connectionwith one'terminal of the lamp, and means on the shade in electricalconnection: therewith for supporting the shade andfor engagingconductors 0t electrical circuits fortestingsame. is n v i. A device ofthe character described comprising a lamp shade having means forembracing a lamp socket member for electrical connection with oneterminal of the lamp, and a spindle extending from the shade inelectrical connection therewith for supporting the shade and engagingconductors of electrical circuits for testing same.

5. A device of the character described comprising a lamp shade havingmeans for embracing a lamp socket member for electrical-connection withone terminal of the lamp, and, a supporting hook carried. by said shadeat one side thereof and in electrical connection with the shade toengagea supporting member and close the circuit of the lamp for testingpurposes.
